Official Audio-gd Sparrow thread - Page 46

post #676 of 724

Hi all. Newbie here.

 

I am about to take delivery of a new Sparrow A-BNC with DIR9001 receiver... and I'm a bit worried I may have chosen poorly. My headphones are Grado SR325i... only 32ohm and pretty sensitive. Is the Sparrow going to overpower my phones?

post #677 of 724

No, I use my Sparrow with my IEMs and it just makes the sound quality better. Everything sounds cleaner, smoother, and more natural.

Eraser - thanks, that's a relief. I also have a pair of Etymotic ER4P which sadly I've broken, but contemplating getting them repaired and maybe even converted to ER4S. Good to know the Sparrow can work even with sensitive phones.

 

Carl - I read this whole thread before posting. If this wasn't just my second post I'd probably be quite rude in my reply to you. For now I'll just say that you're clearly in the wrong hobby. You should find something else to do.

Well it's here. I got the BNC version, but the socket on the back and the switch on the front still have "USB" silk-screened on them. 

 

Initial sonic impressions are that it's very clean, detailed, dynamic, with good extension at both ends. It does respond to a high quality BNC input a la my Audiophilleo 2 USB/SPDIF interface - it's noticeably more open and detailed compared to plastic toslink straight from the Mac. With next-to-no burn in time I don't want to come to any firm conclusions, but at this early stage I'm finding the mid-bass to be a bit thick. Not sure whether that's the Sparrow or my phones.

 

It's also bloody powerful. The volume knob starts at 7 o'clock and I can't get past about 9 on most modern recordings without fearing for my ears. This is with Grado SR325's. The positive side of this is that I'll be able to explore harder-to-drive phones too.

 

Compared to the headphone socket on the MacBook Pro and an iPhone 3GS... well let's just say I'm very impressed with the quality of what people get by default but I feel there's definitely room for products like the Sparrow. I'll try some blind testing when I can to see how reliably I can pick the difference :)

That's not so much power as simply high gain settings. However, it does (going by spec) have quite a bit of power.  I'd agree it is very slightly on the warmer/thicker side of things.

@ kdoot:  The "A" was very warm to me.

 

I need to buy another "B" so I will feel comfortable loaning my DAC1 out...

Just received my sparrow from a member here. Looking to keep this thread going with peoples thoughts.

post #683 of 724

I just bought the A-BNC version to replace my Zero DAC which I had for a few years now.

Here are some thoughts :

1. Drives my Etymotics ER-4P just great 

2. I am not 100% pleased with how it works with my Sennheiser HD-600s . Somehow it feels like the power is lacking and I had to turn the volume knob all the way to get the volume I like.

To be frank I do the same with Zero DAC so maybe its just my hearing :)

I am feeding it with spdif optical out from my creative sb x-fi.

The main audio volume on the creative is about half way. Wave out is set to the max. 

Could it be due to insufficient burn in or is Sparrow really not enough to drive HD600? 

post #684 of 724

i run an xfi to my audio-gd fun. I get the best results by using wasapi out from foobar 2000. This effectively sets my volume to full amongst other things. I set the volume through my dac to maintain quality. This wont work though if you like to control the volume in windows/osx/or whatever.

post #685 of 724

Well I dont mind using the volume knob on the dac.

I am just kind of afraid to use it too much so as not to cause any damage to the device.

Also I use winamp with kernel streaming.

Anyway my question is really about suggested volume for hd 600's and required burn in.

Edwin suggested 300 hour total burn in time on it (100 hour done by them) so I am asking what is your experience with burn in with this dac.

post #686 of 724

There isn't a set standard... but I think you're "supposed" to set the volume on your computer to 100% and then use your amp only to control the volume.

post #687 of 724

Yep...as I understand it, all volume control done via computer is digital volume regulation, which does nasty things to music.  Adjusting the volume through the amp or DAC using a physical pot is using analog attenuation to increase or decrease the volume, which doesn't distort things the way digital regulation does.

Ok then, thanks for your suggestions

I will try to set the windows volume at 100% and see how it goes.

One more question though :
The dac seems to be getting pretty warm to touch , should I be worried?

 

post #689 of 724

Don't worry it's supposed to be getting warm, it's a Class-A amp. Also, some say that you're supposed to let it warm up first for performance to be the best.

I had that problem when I first got mine, and it was suggested to me that my headphone jack might not be fully inserted, and sure enough that was the problem.
